Title: Low-impedance excessive-voltage protecting circuit
Inventor: DANIERU BII KAASON
IPC: H02H9/04
Filed: 1992-01-27
Abstract: PURPOSE: To prevent a measuring circuit connected with an output terminal, by making the impedance between the input and the output terminals high or low, according to an input voltage. CONSTITUTION: When an input signal is in a desired range, MOSFET's 24, 44 turn on, and the impedance between an input terminal 10 and an output terminal 20 becomes low. When the input signal exceeds a positive desired maximum value, the MOSFET 24 is biased to be in the OFF state, and an input current is limited by a high impedance, thereby eliminating the signal from the output terminal 20. When the input signal exceeds a negative desired maximum value, the MOSFET 44 is, similarly, biased to be in the OFF state. Bipolar transistors 30, 48 increase the changing speed of the MOSFET's to the OFF state.

Title: Zoom lens barrel for camera
Inventor: OKAWA SHINICHI
IPC: G02B7/10
Filed: 1989-02-15
Abstract: PURPOSE:To decrease the numbers of cam grooves and guide grooves and to increase the strength of the lens barrel itself by restricting a 2nd lens group and a 3rd lens group slidably by a guide bar in a moving cylinder and allowing the lens groups to move forth and back by the cam movement of a cam cylinder. CONSTITUTION:When the cam cylinder 14 is rotated, the moving cylinder 12 is restricted by the 1st cam groove 32A of the cam cylinder 14 to move forth and back. At the same time, the 2nd lens group 20 and 3rd lens group 26 are also controlled by cam grooves 32B and 32C to move forth and back. At this time, only guide pin from each of a 2nd lens support frame 22 and a 3rd lens support frame 28 is fitted in a straight groove of a fixed cylinder 10 or a cam groove in the cam cylinder 14 and its forward-backward movement is restricted by guide bars 24 and 30. Consequently, the numbers of the straight grooves formed in the fixed cylinder and the cam grooves formed in the cam cylinder decrease and the lens barrel itself becomes strong.

Title: Document processor
Inventor: UEDA HIROYUKI
IPC: G06F17/22
Filed: 1984-02-29
Abstract: PURPOSE:To attain the interchangeability among documents different in type with use of the resources of conventional software and hardware as they are, by using a means which converts the 1st recording type into the key stroke train information, an input means which selects either one of both input information, a control means connected to said input means and a means which inhibits the display processing of said control means. CONSTITUTION:A key stroke train converter CNV reads the document information from a floppy disk device FD. If all document information are stored in a memory WKM in the form of the key stroke trains, the CNV closes AND gates G1 and G2 via signal lines L1 and L2. Then the key stroke train is led to a processor PROC from the WKM via an OR gate G3, and the document is automatically processed. When all document information are written to a floppy disk, the CNV opens the gates G1 and G2 to perform the function of a normal word processor. Thus an undesired key input is inhibited by the gate G1 and at the same time the unnecessary display processing is inhibited by the gate G2. This attains a high-speed operation of a document processor.

Filed: 1984-02-28
Abstract: PURPOSE:To permit the lowering of the necessary working precision by supporting the lower edge part of a rod onto the bottom wall part of a supporting cylinder, keeping a play in the radial direction, in an inverted type suspension apparatus. CONSTITUTION:The lower edge part of a rod 13 is installed onto a slip-off preventing member 41, keeping a play in the vertical and lateral directions, so as to be freely shifted in the radial and axial directions for the bottom wall part 35a of a supporting cylinder 35.
